After inserting the Eargo device
When first inserting your devices, they undergo an active calibration process for 30-60 seconds. During this time they may ring a bit. Don’t be alarmed – this is normal. It’s just the devices adjusting their tuning to your specific ear canal. Kind of like how an orchestra takes a minute or so to make sure they’re in tune with one another.
If the ringing doesn’t stop, try rotating the device slightly to make sure the microphone is not touching the ear canal and causing feedback. You can also remove and re-insert the device.
